I have a sewer smell in my house and can’t find its location?


Sewer odors can permeate into house in numerous ways. The first thing to do is to fix the most obvious things that are outlined below.

  • One of the most common reasons for sewer smells in dried out trays under sinks, showers,  baths and toilets drying out and letting sewer odors back into the property. For fixtures that are rarely used you should make an effort to run water through all fixtures at least once a month.
  • Poorly vented waste pipes can pull water out of traps in adjacent fixtures. Gurgling sounds (in traps to adjoining fixtures) when another fixture is being emptied of water is a good indication of inadequate ventilation in waste pipes.
  • Disconnected or poorly fitted foul vents in walls and attic spaces.
  • Gaps around toilet waste pipes in concrete floors.
  • Cracked or broken waste pipes can let out sewer gases but not leak liquids into the property.
  • Poorly located foul vent pipes beside windows, doors and wall vents.
  • Damaged or poorly fitted foul drain covers to outside of house beside doors and windows.
